Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mechanics tensile test, more particularly to a kind of mechanics tensile test sample preparation device of regular packing. BACKGROUND

[0002] Tensile test is the most widely used mechanics performance test method, and tensile test can determine a series of strength indexes and plasticity indexes of materials. Before tensile test, sample preparation is carried out according to relevant standards and material characteristics, and the quality of sample preparation affects the accuracy of tensile test data. Generally, for the tensile test of metal materials, it is necessary to avoid material heating, work hardening, deformation and other phenomena during sample preparation, and to ensure the consistency of sample preparation as much as possible. Regular packing is composed of several mutually parallel stacked corrugated metal sheets, and most of the corrugated metal sheets have regular punched round holes. The purpose of mechanics tensile test sample preparation of regular packing is to test the mechanical properties of corrugated metal sheets of regular packing after use, and the test sample preparation needs to reduce the corrugated metal sheet to the flat state without bending, and then clean the surface impurities and carbon to prepare the sample.

[0003] Most of the metal materials have high hardness, and in the process of sample preparation, wire cutting technology can prevent overheating, work hardening, deformation and other phenomena of materials. Wire cutting has the advantages of small machining allowance, high machining precision and no damage to the mechanical properties of materials. As long as the material is conductive or semi-conductive, it can be processed by wire cutting, and continuous processing can be realized without manual operation after programming. Therefore, most of the metal material tensile samples are processed by wire cutting.

[0004] (1) Patent CN205981817U discloses a kind of electric wire cutting sample preparation machine for plastic plate or sheet, which comprises a base plate, a support is arranged on the base plate, and a motor is also arranged on the base plate;A connecting seat is arranged on the support, and a steel wire saw is arranged on the connecting seat, the lower end of the steel wire saw is connected with a gear arranged below the base plate, and the gear is correspondingly matched with the motor through a mechanical transmission device, so as to cut the sample.

[0005] (2) In addition to the above scheme, the sample preparation method of individual mechanical test uses mold technology, and the structure of the mold is different according to the sample preparation requirements of the material, such as the patent CN216870156U discloses a dog bone type soil body tensile test sample preparation mold, which belongs to the technical field of sample preparation device for tensile test, comprising an opening mechanism and a fixed bottom plate, the opening mechanism is sequentially connected by a first clamping section mold, a tensile mold group and a second clamping section mold to form a cavity structure, and the opening mechanism is detachably installed on the fixed bottom plate. The utility model can conveniently produce more soil body tensile samples of different lengths through the opening mechanism and the fixed bottom plate with screw holes, and the strength of the soil body and the change rule thereof under different sizes can be studied, and the tensile properties of the soil body can be conveniently understood.

[0006] (1) At present, the mechanical tensile test sample preparation of structured packing adopts the method of placing wood and using a hammer to knock it flat or using a press to flatten it during the process of reducing the corrugated packing into a flat plate. There is uneven leveling during the process, and the mechanical properties of the regular packing sheet are damaged during the knocking and flattening process.

[0007] (2) Although the wire cutting technology can meet the cutting of structured packing metal sheet samples, most regular packing metal sheets have a porous structure, and it is necessary to ensure that the porous structure in the sample is centered and uniformly distributed during sample preparation. If the wire cutting technology is used, the operation process of each point is increased, and the inaccuracy of the pointing accuracy affects the sample preparation quality. The common problem is that the porous distribution of the cut sample is uneven, which affects the mechanical tensile test results. Utility model content
